Re: Link Directly to Blogs' Author Posts
Gotcha… just briefly glanced the post 
So you just want to list a bunch of blog links that the displayed user is a contributor to?
Blog roles were removed in BP 1.2.3 due to performance reasons. However, you might want to look for a WPMU-specific function for this.
Try get_blogs_of_user():
